IRG1 investigates how magnetism affects electron transport in a broad class of novel materials with unusual magnetic states. The presence of strong interaction between electrons leads to a variety of magnetically ordered states ranging from ferromagnetism, ferrimagnetism, antiferromagnetism, spin density waves, and the spin-Peierls state. Strong interest in how magnetism affects charge transport has come from the growing importance of magnetism in electronics applications. The materials include oxides (cobaltates, spinels, pyrochlores) in which long-range magnetic order is suppressed by ???geometric frustration???, two-dimensional (2D) ultra-high-purity electron gases in heterostructures, and materials displaying unusual magnetic effects stemming from strong correlation and superconductivity (Mott insulators and cuprates).
